Roy Halladay’s shoulder problems are expected to sideline him for 6-8 weeks and Todd Zolecki of MLB.com has an interesting note about the ramifications of the injury beyond this season.

Halladay signed a three-year, $60 million deal with the Phillies in December of 2009 to facilitate his trade from the Blue Jays and the contract also includes a $20 million option for 2014 that vests if he throws 415 total innings between 2012 and 2013, including at least 225 innings in 2013.

Even for a workhorse like Halladay reaching those marks was hardly guaranteed before the injury and now it’ll be almost impossible. Halladay has thrown just 72 innings this season, which means he’d have to throw another 343 innings between now and the end of next season.

Zolecki also notes that there’s nothing keeping the Phillies and Halladay from re-doing the contract if both sides want to avoid a breakup after next season, but for now at least the shoulder injury has likely cost him $20 million.

Jon Heyman of FanRag Sports reports Thursday that the Orioles “are said to have begun fielding calls of interest” on superstar Manny Machado and “are close to the point of seriously weighing whether to trade him.”

You’d think it would be a no-brainer for the last-place O’s to flip Machado — an impending free agent — for prospects, but Heyman notes there is “still a question whether or not longtime Orioles owner Peter Angelos” will give the go-ahead. One person familiar with the situation put it a “50-50” likelihood. Another suggested that it would take a massive return, which, sure.

Machado entered play Thursday with a sensational .328/.405/.635 batting line, 15 home runs, and an MLB-leading 43 RBI in 49 games. It’d be a real shock if he’s still wearing an O’s uniform by the end of July.

Heyman reported previously that at least nine teams made aggressive plays for Machado this winter, including the Cubs, Phillies, Dodgers, Indians, Diamondbacks, Yankees, Red Sox, White Sox, and Cardinals. A whole lot of those teams still make sense here in late May — maybe all of them except the White Sox.
